A partial loss of smell is often temporary and commonly caused by nasal inflammation, allergies, or a recent viral infection. To help restore your sense, you can try: 1. Saline nasal rinses to clear irritants and soothe nasal passages. 2. Corticosteroid nasal sprays: Generic options like fluticasone or mometasone can effectively reduce swelling in the nasal lining if allergies or polyps are the cause. 3. Olfactory training: Sniffing distinct scents (like lemon, rose, or eucalyptus) daily can help retrain your brain's smell receptors. Please consult a healthcare professional or an ENT specialist for a proper evaluation before starting medicated sprays.
